To all whomit may concern: I

lie it known. that; l; Jain-1s Nmo a subject" of the Kinu of lreatBritain and irrlauth and a resil. lt cl" East; ll au'i l lFfx, lflugland5 have invented certain new and useful Improvements in .Mjipai'atus forDistilling Shale and other l litumiumls Substances; and I do herebydeclare the following to be a full, elear and exact description of thesame. V

This invent'ap relates to improvements in apparatus 1 distilling shaleand other bitum'inous s i. ances.

The inve 1 ion has for its objeetto insure the gradg al and uniformheating of the shale oipthe like being treated, and. to avoid theupeltiren heating which occurs at the sides and 'ee nt'er pfithecustomary vertical retorts, and the di'lliculties of firing incidentalto the use of horizontal retorts.

According to the present invention the improved retort or still hassides of astepped cylindrical form ation, and is arranged witlit itswidest diameter uppermost and its smaller dia meter lmvermost so thatits inside presents series of horizontal or approximately lmrizontalconcentric ledges Ihe retortis setin the combustion chamber or flue of a"furnace so that the outside? I v f the retort exposed to the heat ofthe latter, the lowermost part of the retort being suh jeotcd to thegreatest heat. Inside the retort, are arranged rotary rakes or armswhich are adapted to sweep around, said ledges and "5 gradually Work thesubstance under treatilnent, which is fed onto the highermost led gethrough suitably placed hoppers, around the ledges and down from ledget0 ledge. The exl'iausted shale is discharged'at the bottom 40 of theretort, and the vapo evolved from the shale are led off from the stillhead to any suitable corulensing apparatus wherein the products arerecoveredin known main nor. The substance under treatment is thus '45caused to take aprolonged path in deseending, through the retort to thedischarge out-. lot and its Whole mass is gradually. and evenlysubjected to the increased tempera tare. l The invention is illustratedinthe accompanying drawings, in whiehz Figure L is a sectionalelevation; Fig. 2. is a plan ;-Fig. 3, is a seetionalelevation at rightangles to Fig. 1 Fig. 4, is a sectional Referring to the d awingz s, 1L.is the retort constructed of a stepped eiwyliinlrieijil tin niatiou asaforcsahl.

What I claim as my invention and desire to secure by Leters-Patenfi is:-

' 1. In apparatus for distiliing shale and other bituminous substances,in combination, -21 fu rhace, e retort having sides of a steppedcylindrical formation and arranged in the combustion chamber or flue ofthe furnace with its Widest diameter uppernimsl and. its smallestdiii'meteriowermost so that the inside presents it series of horizontalor approximately horizontal coneentfic ledges of essen- ,ing ditimeter,means for feeding the n etei-iel onto the highermost ledge, and meansfor Working the material aroundihe ledges and down, from led 'e to lodgeto a discharge UHF let, substentielry as described.

2. In'appmratus for (instilling shale andother bituminous substances,inv combination, uifurnace, :1 io'loi'bhaving sides ofei steppedcylindrical formation and arranged in the combustion chamber or flue ofthe furnace with its Widest diameter uppermost and its smallest diameterlowermost so that the inside presents 21' series of horizontal oreppi'oximai'ely horizontal concentric ledges, means for intermittentlyfeedingthe material onto the highen'nostt ledge, and rotary rakes orarms adapted to sweep around said legee and gradually ork the suostenee.
